Answer:

1 m by 189 m

Step-by-step explanation:

The perimeter is 2(70+120)=380.

The area is (70)(120)=8400.

If we let the park have a width of 1 meter and a length of 189 meters, then the area will be 189 square meters, which is smaller than 8400 square meters, as required.

The line y = kx + 6 is a tangent to the graph of
Wittaler [7]

Answer:

Step-by-step explanation:

For equating the equations, you get

 

x2 + kx - 3x + 4 = 0               eq1

 

 

Setting the derivative of f(x) equal to 3 yields

 

f'(x) = 3

 

2x + k = 3                           eq2

 

 

Now we substitute the value of k from eq2 into eq1.

 

x2 + x(3 - 2x) - 3x + 4 = 0

 

 

Solve for x from this equation.  Then plug in the value of x into eq2 to solve for k

Statistics??? Construct a 95% confidence interval for the population mean. Assume the population has a normal distribution. A sa
antiseptic1488 [7]
Given:
μ = $3120, population mean
σ = $677, population standard deviation.
The population is normally distributed.
n = 20, sample size.

At the 95% confidence level, the confidence interval is
( \mu - 1.96\frac{\sigma}{ \sqrt{n} }  ,\, \mu + 1.96\frac{\sigma}{ \sqrt{n} })

1.96(σ/√n) = 1.96(677/√20) = 296.71
Th confidence interval for the mean is
($2823.29, $3416.71)

Answer: ($2823.29, $3416.71)
